Can you use the turtle beach XLC on a PC?

Yes, you can. But, as what is happening to me, the computer is not recognizing the exterior headset. It is just showing the default computer mic and speakers. I am on Windows 7. I assume this is because the headset is not usb. Also, I found that the mic doesn't pick up Words with "s" that well.

You can buy a 2.5 MM Female to 3.5 MM Male adapter for the microphone output as well as a standard RCA R/W to 3.5 MM adapter for the audio output. Doing so will convert your headset into a PC headset.

Note: If you do this you may need to plug the USB cord into a wall outlet to produce sufficient power for the microphone to work properly.
